Pork-liver flavored chewable tablets for easy administration

If you would like to save money and/or if your dog has allergies, please ask your veterinarian about this product.

How does Iverhart Plus work?
Ivermectin eliminates the larval (immature) form of Dirofilaria immitus. This prevents the development of the adult stage of the heartworm. Ivermectin works by causing paralysis of the parasite which eventually causes its death. Pyrantel pamoate kills adult hookworms (Ancylostoma caninum, A. brasiliense, and Uncinaria stenocephala) and roundworms (ascarids - Toxocara canis, Toxascaris leonina)in the intestine.

Is there a generic equivalent available?
Iverhart Plus is the generic equivalent of Heartgard Plus.

How is it given?
Iverhart Plus chewable tablets are given orally and will be equally effective whether chewed or swallowed whole. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that part of the dose is not lost or rejected.

Iverhart Plus must be administered monthly, preferably on the same date each month. Drs. Foster and Smith recommends (and our guarantee requires) that Iverhart Plus be given year round, although some veterinarians may recommend giving it only during the mosquito season. If given seasonally, the first dose must be given within 30 days of the dog's first exposure to mosquitoes. The last dose must be given within 30 days after the dog's last exposure to mosquitoes. The tablet kills the parasites acquired during the previous month. (The tablet given December 1st treats exposures to heartworm during the month of November.)

Always follow the dosage instructions provided by your veterinarian. If you have difficulty giving the medication, contact your veterinarian.

This medication should only be given to the pet for whom it was prescribed.

What results can I expect?
Iverhart Plus will kill the immature heartworms the dog was exposed to in the preceding month. It will treat an intestinal infection with adult hookworms and roundworms.

What form(s) does it come in?

What should I discuss with my veterinarian while considering Iverhart Plus?
Talk to your veterinarian about the heartworm testing that is recommended before starting your dog on a heartworm prevention program or switching from one preventive to another.

Collies or other herding breeds may have a reaction to ivermectin if given over the recommended heartworm prevention dose. If your dog is one of these breeds, and your veterinarian has prescribed Iverhart Plus, observe your pet for at least 8 hours after giving the medication for weakness, staggering, dilated pupils, trembling, drooling, or pressing the head against a wall. Contact your veterinarian immediately if you see these signs.

Some intestinal parasites, such as hookworms and roundworms can be spread to people. Talk to your veterinarian about other measures you can take to prevent your pet from being infected with intestinal worms, and protecting yourself.

Notify your veterinarian of any other medications or supplements your dog is taking, and also if your dog has had any reactions to previous medications.

I have been giving my dog Heartgard Plus for years. Will Iverhart Plus provide him with the same protection?

A.

Yes. Iverhart Plus has the same exact active ingredients, Ivermectin and Pyrantel, the same quality, and same strength as the Heartgard Plus brand, but costs less. Iverhart Plus was approved by the FDA in 2001 as a bio-equivalent to Heartgard Plus. It offers the same protection against heartworm disease and against intestinal roundworms and hookworms as does Heartgard Plus.

I have heard that certain dogs have food sensitivities to the beef in some heartworm protection products. How does Iverhart address this issue?

A.

Over the years, food allergies have become a concern to veterinarians. Iverhart Plus is preferred by our veterinarians not only because it is more economical, but because it is pork-based and perfect for dogs with food allergies especially sensitivity to beef products.

Iverhart Plus delivers all of the benefits of Iverhart in addition to eliminating roundworms and hookworms, which can cause intestinal disease. In addition to Ivermectin, Iverhart Plus contains Pyrantel, which has been shown to be effective in the removal of certain intestinal worms.

Adult heartworms lay very tiny larvae called microfilariae, which circulate in the blood. They enter a mosquito when it sucks the blood of an infected animal. They mature in the mosquito and then enter the animal's skin when an infected mosquito bites the animal. When the larvae reach about 3 inches, they migrate to the animal's heart where they grow into adults, sometimes reaching a length of 14 inches.

The adult worms can obstruct the different chambers of the heart and the various large blood vessels leading to and from the heart and lungs. In severe infections, other organs, such as the liver, can also be damaged.

I have heard that Collies and other herding breeds have trouble with Ivermectin. What can you tell me about this?

A.

Collies or other herding breeds may have a reaction to ivermectin if given over the recommended heartworm prevention dose. If your dog is one of these breeds, and your veterinarian has prescribed Iverhart Plus, observe your pet for at least 8 hours after giving the medication for weakness, staggering, dilated pupils, trembling, drooling, or pressing the head against a wall. Contact your veterinarian immediately if you see these signs.
